DOUBLE-FOLDING DOORS
Double-folding doors are suitable for doorways between 1 and 1.5m wide and are appropriate where  interior space limitations preclude the use of gliding doors. The leaves are carried on steel shafts, which are suspended from the overhead mechanism and located at the bottom by bearings bolted to the step. Primary and secondary leaves are joined by a pair of substantial maintenance-free hinges.
HANDRAILS
The door is normally supplied complete with a diagonally ascending handrail finished in yellow polyester. If a handrail is not required, a small handle is fitted near the top of the door to enable it to be pulled open in an emergency.

NOSING RUBBER
The meeting edge of each door leaf has an 80mm hollow rubber nosing which features an overlapping tongue to ensure a good seal between the leaves.

APERTURE SEALS
Rubber seals ready-mounted in an extruded aluminium section are provided for fitting to the vehicle body at the top and sides of the doorway. A rubber seal is preferable for the top of the door, but is practical only where the door can open without passing outwards through the seal. If interior space limitations make it necessary for the opening door to pass outwards through the top seal, then a nylon brush seal must be used instead. The bottom seals are nylon brush sections mounted adjustably on the door leaves.
